In the Xuangguang Realm, spiritual energy and machinery coexist, but the world has been polluted by "Entropy Blight." Humans mutate into monsters known as the Fallen Cultivators, while the six great sects monopolize resources through the Spirit Nexus Towers, watching as those at the bottom sink into despair.
Lu Xun, immune to the Entropy Blight that destroyed his homeland, unexpectedly becomes one with Youye, an aggregate of desires born from the Heart Abyss. He awakens the ability to infiltrate the collective human subconscious known as the Heart Abyss. It teems with desire beasts and remnants of civilization, serving both as a battlefield where he can hunt "Thought Cores" to cleanse the Entropy Blight and as an abyss that devours personalities.
As he counters traditional spiritual cultivation with a Heart Refining system and shatters the chains of the establishment with the power of emotions such as "Fearfire" and "Love Spring," he stumbles upon a shocking conspiracy by an elder of the Ink Sect: twisting the redemption vaccine of the ancient civilization Gaia into a weapon of mass destruction, all to earn the right to ascend to a higher dimension.
The mechanical ascension of Yun Jing, a cleaner for the Spirit Nexus Towers; the battle between the Machine Race and humanity for control of consciousness; the cold indifference of the Observer civilization... Amid choices between revenge and protection, Lu Xun must face the cruelest truth: the ultimate weapon against the Entropy Blight may lie in the abyss within every human heart.
As Youye tears through Thought Cores to cleanse the corruption, and Yun Jing uses consciousness as a wall to shut out the Heart Abyss's whispers, this civilization's redemption, kindled by human nature, will finally ignite a new dawn over the ruins.
